Latest Patents

Mottram's latest patents include a method and apparatus for concentrating oxygen. This invention features an oxygen concentrator apparatus that utilizes two zeolite beds and alternating, pressure-controlled pressurization and exhaust cycles. It incorporates a swash plate cylindrical pump with a pressure-sensitive idle mode. The improved oxygen concentrator apparatus boasts an isothermal, high-volume, low-pressure air flow system with unrestricted air conducting lines and ports for enhanced efficiency in oxygen production. Additionally, it includes a unique rotary vane pump designed for isothermal air pumping, featuring a precision collet mounted rotor with centering apparatus, tapered vanes for reduced wear, and a combination cast iron pump chamber liner with an external aluminum finned casing for durability and heat dissipation.

Another notable patent is a pressure swing adsorption oxygen concentrator that employs multiple zeolitic molecular sieve beds. This invention alternates the pressure and air flow in each bed, enhancing the purity of the oxygen-enriched gas produced. The changes in this system are initiated by a pressure-sensitive transducer that detects a predetermined upper pressure limit. The air compressor drive includes a spring-biased swash plate that reciprocates the piston rods of reciprocating piston compressor pumps.
